if i were outside of my house, i would hide stuff in my shoes...
if it's in my house, it would be.... well i dont hide stuff in my house
i hide it in a bank or something... or it would be chained to me at all times...
my cellphone has a chain that can be attached to my pants... (i have learned a lesson )
the chain also makes a good accessory

Hmmmmm, that's a tough one. I've got a pound of silver coins. I suppose If I had some great need to hide it, I'd bury it in the yard in the spot where I bury my pets. I can't forget it since its it would be with the bones of my birdies. But for now, I just keep them in an old jar at the top of my closet.
